to -painting instruments striping instruments.

An object of the invention is to provide an instrument for striping aperimeter.

Another object of the an instrument for apply width throughout itslength a work piece and in unit the edge.

Another object of the an instrument adaptable work piece adjacent itsinvention is to provide a stripe of uniform djacent the edge of 1 spacedrelation to invention is to provide for applying a stripe of paint ofuniform thickness and width throughout its length adjacent the edge of awork piece.

A further object of the inv ntion is to provide a striping instrumenthaving a guide roller arranged for coaction with piece, and a feedingfor delivering paint the perimeter of awork means operated by the rollerto the work piece in spaced relation to its perimeter and in proportionto the rate of movement of the instrument.

A further object of the invention is to provide a striping instrumenthaving a container adaptable for the reception of a liquid paint, apositive feeding means connected with the container and an operatingmeans for ranged to operate the feeding the feeding meansiafmeans toapply paint to a work piece n a stripe uniform y Spaced with respect tothe perim A still further object of the invention'is for paintingstripes of uni;

s and in spaced relation work piece, the instrument that the paint willbe applied at a rate proportionate to the rate of movement of theinstrument.

Other objects of the invention will appear from the followingdescription taken in connection with the accompanying drawing, whichforms a part of this specification, and

in which:

Fig. 1 is a side elevation of an instrument illustrating the positionthereof when applying a stripe to the edge of a louver;

Fig. 2 is a front elevation;

Fig. 3 is a top plan vi removed; and

ew with the cover plate Fig. 4 is an enlarged top plan view partlybroken away and partly in section.

Referring to the drawi ng for more specific de tails of the invention,represents a body portion comprising a rectangular block having atransverse bore 11 in which is threaded a plug 12. The plug has an axialbore 13 in which is positioned a sleeve 14 provided with a flange 15 anda reduced end porti on 16 on which is positioned a coil spring 1'?intermediate the flange 15 and the end of the plug 12. The sleeve 14 isaxially bored as indicated at 18 and threaded in the sleeve is acontainer 19 having a cap 20 provided with the conventional vent 21. Thespring 0 bears against the inner end of the plug 12 and exerts pressureagainst the flange 15 in an axial direction so that the tapered portion9 of the sleeve is held in sealed relation against the edge of the plugforming the outer end of the bore 18. This spring pressure is such as topermit manual rotation of the sleeve and thus the container carriedthereby can be rotated.

Suitably secured on the body portion 10 is a plate 22 having positionedtherein a pump mechanism 23, the intake 2% of which is connected by apassage 25 to the bore 11, which communicates with the container 19, andthe outlet 26 of the pump mechanism is connected by passages 27 and 28to a recess 29 in which is fitted an arm 30 axially bored as indicatedat 31 to communicate with the passage 28. Positioned in the free end ofthe arm 3011s a nozzle 32, the passage in which communicates "with'thepassage 31 in the arm 30. The nozzle isinaiplane substantially parallelto one side of the body portion. Positioned on the plate 22 over thepump mechanism is a'cover plate 33 and the plates 22 and 33 are suitablysecured to the body as'by screws.

The pump operating means comprises a shaft 3e" suitably connected to oneof'the'operating 3 elements of the pump and positioned on the shatt 341sa roller 35 adapted to function as a guide and an operating means forthe instrument. As shown, the shaft 34 extends from the bottom of theinstrumentwith its axis in a plane substantially parallel to the nozzle32 and the operating roller on the shaft is positioned for rotationsubstantially at right angles to the nozzle and adjacent to thedischarge end thereof, so that upon engaging the perimeter of a workpiece with the roller, the nozzle is positioned for applying a stripe inspaced relation to the perimeter of the work piece to be operated upon.

The body of the instrument is provided with depending lugs 36 arrangedin oppositely disposed relation. Each of these lugs supports a plate 37,the upper end of which is curved outwardly as indicated at 38 to providea suitable finger grip, As shown, the plates 37 are secured to the lugs36 by screws 39, and an auxiliary finger grip 40 is provided on one endof the instrument, arranged in spaced relation with respect to one ofthe finger grips.

It will be observed that the relation of the operating means, the roller35, with respect to the nozzle 32 is such that upon engaging the roller35 with the edge or perimeter of a work piece, the nozzle will bemaintained in the same spaced relation to the perimeter whether theinstrument moves in a straight or curved path, and that the feedingmeans which is operated at a rate proportionate to the rate of movementof the instrument, will deliver paint or lacquer from the container tothe nozzle for application on the work piece adjacent the perimeterthereof and and having a tapered portion adapted to frictionally engagein sealing relation with the plug, spring means in the body cooperatingwith the plug and sleeve to normally maintain frictional engagementtherebetween, a fluid container fixed to and communicating with thesleeve, and a nozzle carried by the body, and communicating with thesleeve.

2. In a striping instrument, a body having a fluid dispensing nozzleextending therefrom, plates secured to two opposite sides of the body,said plates terminating in outwardly curved grips extending above thetop of the body, and an angular finger grip associated with one side ofthe body and having a portion in parallel relation with one of theplates.

3. In a striping instrument, a body having a nozzle extending therefrom,a sleeve carrying a fluid container rotatably mounted in the body, saidcontainer communicating with the nozzle, and means including a springnormally holding the sleeve in sealed relation with the body and in anyposition of rotation.
